BACKGROUND OF THE INVENTION Field of the Invention

Embodiments of the present invention relate to a vehicle for preventing a collision with an obstacle, and a method for controlling the same.

Description of Related Art

A vehicle is an apparatus to move on the road by the driving of vehicle wheels for the purpose of transporting persons or cargo.

In recent times, the vehicle may include at least one of an ultrasonic sensor, an image sensor, a laser sensor, and a Light Detection And Ranging (LiDAR) sensor, each of which can substitute for the user's field of vision, may collect information related to traveling of the vehicle using at least one sensor, may recognize a forward obstacle, and may output the recognized information to allow the vehicle driver to recognize the obstacle resulting in the prevention of a traffic accident.

When the vehicle recognizes an object using an image sensor, the shadow of an ego vehicle or the shadow of a peripheral vehicle may be misunderstood as a vehicle, or false alarm or non-alarm may occur by the direct sunlight, an object reflecting light, or backward high-intensity light source or a low-illuminance environment.

Although the presence or absence of an obstacle can be confirmed when the vehicle recognizes the object using the distance sensor, such as an ultrasonic sensor, a road sign, a slope, or a speed bump may be misinterpreted as an obstacle. In the present case the vehicle may have difficulty in correctly recognizing the object.

In addition, it is impossible for the vehicle to recognize roads or buildings located approximately 200m or more from the vehicle in a forward direction when the vehicle desires to recognize the target object using a LiDAR or radar sensor. The vehicle also has difficulty in correctly recognizing the target object when unexpected situations (e.g., a road having no lane, pothole, bad weather, etc.) occur, resulting in a higher difficulty to maintain safe driving.

The information disclosed in this Background of the Invention section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person skilled in the art.

Referring to FIG. 7, the vehicle may confirm the traveling road type on the basis of navigation information and communication information, and may recognize the current traveling lane on the basis of image information.

The vehicle may determine that the road type is a six-way lane (i.e., round-trip 6-lane road). When the traveling road is a second lane from among six lanes, the vehicle may determine that the probability of existence of another vehicle located in the left region of the ego vehicle is equal to or higher than a reference probability, may set a left border lane of the left lane to a left borderline of the existable region of another vehicle (i.e., another-vehicle existable region), may determine that the probability of existence of another vehicle located in the right region of the ego-vehicle lane is equal to or higher than a reference probability, and may set a right border lane of the right lane to a right borderline of the existable region of another vehicle, establishing another-vehicle existable region (VA).

The vehicle may confirm that the road type is an expressway, may determine that the probability of existence of the pedestrian located in the right and left regions of the ego vehicle is less than a reference probability, and may set the ego-vehicle existable region (VA) only with respect to the forward region of the ego vehicle.

That is, the vehicle may not establish the existable region of the pedestrian with respect to the right and left regions of the ego vehicle.

As shown in FIG. 8, the vehicle may confirm the traveling road type on the basis of navigation information and communication information, and may recognize the current traveling lane on the basis of image information.

The vehicle may determine that the road type is a four-way lane (i.e., round-trip 4-lane road).

As shown in FIG. 9, the vehicle may confirm the traveling road type on the basis of navigation information and communication information, and may recognize the current traveling lane on the basis of image information.

When the vehicle determines that the road type is a two-way lane (i.e., round-trip 2-lane road), i.e., when the traveling road is a one-way lane (i.e., one-way road), the vehicle may determine that the probability of existence of another vehicle located in the left region of the ego vehicle is less than a reference probability, may set the left border lane of the left lane to a left borderline of another-vehicle existable region, may determine that the probability of existence of another vehicle located in the right region of the ego-vehicle lane is equal to or higher than a reference probability, and may set a boundary line of the right detection region from among the detection regions of the image detector and the obstacle detector configured to a right borderline of another-vehicle existable region, establishing another-vehicle existable region (VA).

That is, when another lane is located at a side surface of the recognized traveling lane, the vehicle may establish a borderline of the obstacle existable region on the basis of lane information of another lane. When another lane is not present at the side surface of the recognized traveling lane, the vehicle may establish a borderline of the obstacle existable region on the basis of a boundary line of the detection region of the image detector or the obstacle detector.

In the instant case, the operation for determining that the probability of existence of another vehicle located in the right region of the ego-vehicle lane is equal to or higher than a reference probability may include determining that the probability of existence of another vehicle is equal to or higher than the reference probability due to either one vehicle entering the ego-vehicle lane or the other vehicle parked at one side of the traveling lane. The above-mentioned decision information may be acquired by experimentation and experience, and may be pre-stored.

The right region of the ego-vehicle lane is an opposite lane, a traveling direction of which is opposite to the traveling direction of the ego vehicle. The other vehicle located in the right lane of the ego-vehicle lane is another oncoming vehicle. Therefore, the current traveling lane may be excluded from the right lane.

That is, when the road type is a one-way lane (i.e., one-way road) or when the vehicle travels in the first lane, the vehicle may determine that the probability of existence of another vehicle in the right region of the ego vehicle is less than a reference probability.

That is, since the vehicle has difficulty in acquiring information regarding the right lane when traveling on a one-way lane (i.e., a one-way road), the vehicle may establish the existable region of the obstacle on the basis of boundary lines of detection regions of the image detector and the obstacle detector.

Referring to FIG. 10, the vehicle may confirm the traveling road type on the basis of navigation information and communication information, and may recognize a current traveling lane on the basis of image information.

When the road type is a two-way lane (i.e., a round-trip 2-lane road) and when the vehicle roads on the first lane from among two lanes of the road, the vehicle may determine that the probability of existence of another vehicle located in the left region of the ego vehicle is less than a reference probability, may set the left border lane of the left lane and the left lane of the ego-vehicle lane to a left borderline of another-vehicle existable region, may determine that the probability of existence of another vehicle located in the right region of the ego-vehicle lane is equal to or higher than a reference probability, and may set a right lane of the right road to a right borderline of another-vehicle existable region, establishing another-vehicle existable region (VA).

The vehicle determines that the road type is a city road and a curved road, determines that the probability of existence of the pedestrian located in the left region of the ego-vehicle lane is less than a reference probability, and establishes the existable region HA of the pedestrian on the basis of a boundary line of the right detection region from among the detection regions of the image detector and the obstacle detector.

The vehicle may acquire the actual obstacle information from among the obstacles to be used as the warning targets on the basis of information regarding the established existable region for each obstacle type and the position information of the recognized obstacle corresponding to a warning target (Operation 188). Here, the vehicle may acquire the actual obstacle information from the respective obstacle existable regions. The vehicle may control the warning device 160 and the braking device 170 needed for anti-collision on the basis of position information of the actual obstacle according to the respective obstacle types and the respective obstacle existable regions (Operation 189).

When the vehicle detects the obstacle in an overlap region between the another-vehicle existable region and the pedestrian existable region, the vehicle may also determine the obstacle type on the basis of detection information of the obstacle detected from the overlap region.

Referring to FIG. 10, the vehicle may determine obstacles ob2 and ob4 from among the warning-target objects ob2, ob3, and ob4 to be the actual obstacles on the basis of information regarding the existable region for each obstacle type, and may control the braking device and the warning device on the basis of the determined obstacle position information.

In addition, the obstacle type of the actual obstacles ob2 and ob4 is determined to be a vehicle, and the vehicle may output braking force and warning sound corresponding to the obstacle type (i.e., vehicle).

The vehicle may select the type of the warning sound on the basis of the obstacle type, may control output of the selected warning sound, and may control volume of the warning sound on the basis of the distance to the obstacle.

The vehicle may inform the vehicle driver of a first probability of danger using the warning light of the cluster or side-view mirrors, may perform visual warning by turning on the warning light, and at the same time may inform the vehicle driver of a second probability of danger through vibration of the seat belt.

The vehicle may control the brake to be kept at the pre-fill state wherein immediate braking of the vehicle is possible at any time.

When there occurs an extremely dangerous situation in which there is a high possibility of collision between the vehicle and the obstacle, the vehicle may perform automatic deceleration (i.e., the pre-brake function) within a predetermined scope, may control a Brake Assist System (BAS) function according to the degree of possibility of collision, and may operate the seat belt wherein the driver's body can also be fastened to the driver seat.

As is apparent from the above description, the vehicle and the method for controlling the same according to the embodiments can establish the presence-available region for each obstacle type, and can recognize the obstacle on the basis of the established presence-available region for each obstacle type to increase recognition accuracy of each obstacle, wherein accuracy of alarm sound output and braking function can also be increased according to increased accuracy of obstacle recognition.

The vehicle according to the embodiments can reduce the number of alarm sound output times and the number of braking execution times by increasing recognition accuracy for each obstacle, resulting in reduction of sense of difference. That is, the vehicle according to the embodiments can reduce the possibility of misrecognition caused by misunderstanding of the obstacle.

The vehicle according to the embodiments can reduce the possibility of collision with other vehicles located in a backward direction, caused by execution of false braking.

When the vehicle is an autonomous vehicle, the autonomous vehicle can improve autonomous traveling performance according to reduction in the number of obstacle misrecognition times and the number of incorrect braking actions.
